ABSTRACT
This chapter discusses the methods of collecting intelligence using open source methods and platforms. Open source intelligence is information that is publically available. It is not classified or put under constraints. There are companies such as SurfWatch that charge clients to collect intelligence on the dark web and inform when they find something of concern. Threat intelligence gatherers on the dark web have a task of finding out the new vulnerabilities that are in the hands of cybercriminals. The intelligence gathered from the dark web is directly applicable in cybersecurity efforts. It can be used for a broad scope of applications ranging from crime prevention to improving cybersecurity strategies in organizations. The tool has been used by cybersecurity researchers, law enforcement agencies, penetration testers, and inevitably cybercriminals to quickly access open source intelligence. Google Hacking or Dorking has been used for a long time to find open source intelligence.
